It currently sits comfortably ahead of tracks by international superstars Justin Bieber, Miley Cyrus, and Katy Perry.

Jones — who celebrated her birthday on Monday — posted a tweet celebrating the success of her latest song, which currently sits at #6 on Amazon’s “New Releases” Pop Music chart a little over two weeks after its release.

“What the Heart Don’t Know” is currently ahead of such tracks as Miley Cyrus’s “Younger Now” and “Malibu” (the former of which was performed by Cyrus at the MTV VMAs Sunday night), Justin Bieber’s “Friends,” Selena Gomez and Gucci Mane’s “Fetish,” Kesha’s “Praying,” Fifth Harmony’s “Down,” and Katy Perry’s “Save as Draft,” which currently sits at #85. The Amazon list is updated hourly.

The music video for “What the Heart Don’t Know” premiered last week. The video sees the former Pussycat Dolls singer watching her significant other pack to leave for war, and later dealing with the heartbreaking consequences and emotional repercussions of his sacrifice.
